Our Science
Korean beauty science
meets Canadian standards
We believe what goes near your eyes should be held to the highest standard. That's why we chose peptides over prostaglandins, and Kolmar Korea over shortcuts.
The Story
Born from a question:
why compromise?
Most lash serums on the market rely on prostaglandin analogs — synthetic compounds originally developed for glaucoma treatment. They come with well-documented side effects: iris darkening, periorbital fat loss, and eyelid pigmentation.
Re:Cosm was founded on a simple premise: you shouldn't have to choose between beautiful-looking lashes and safety. By combining Korean cosmetic innovation with Canadian regulatory standards, we created a lash conditioning serum built on peptide science — without the trade-offs.

Hero Ingredients
What's inside
Every ingredient is chosen with purpose. Here's the science behind our formula.
Acetyl Tetrapeptide-3
Capixyl™ Complex
A biomimetic peptide complex, clinically studied by its developers for hair and lash conditioning. Paired with red clover extract, it conditions the lash line and supports the look of fuller, denser lashes.
Biotin
Vitamin B7 / Vitamin H
An essential water-soluble B-vitamin and a natural building block of keratin — the primary structural protein of lashes. Supports stronger-looking, more resilient lashes.
Panthenol
Pro-Vitamin B5
A powerful humectant that penetrates the lash cuticle to deliver deep hydration. Improves lash flexibility, reduces brittleness, and creates a natural, healthy sheen.
Centella Asiatica
Tiger Grass Extract
A time-honored botanical in Korean skincare, known for its soothing properties. Calms the delicate lash line and supports a healthy-looking lash environment.
Hyaluronic Acid
Hydroxypropyl Trimonium Hyaluronate
A modified form of HA that binds to lash fibers, locking in moisture. Creates a protective film that shields lashes from environmental stress.
Glycyrrhizate
Dipotassium Glycyrrhizate
Derived from licorice root, this soothing compound comforts the sensitive periorbital skin and helps reduce the look of redness around the lash line.
Clean Commitment
What we leave out
We believe in transparency. Here's what you'll never find in our formula — and why.
No Prostaglandins
Prostaglandin analogs (bimatoprost, isopropyl cloprostenate) can cause iris darkening, fat atrophy around the eyes, and permanent pigmentation changes. We use peptides instead.
No Fragrance
Synthetic fragrances are among the top sensitizers for the delicate eye area. Our formula is 100% fragrance-free for maximum comfort.
No Parabens
We use modern, gentle preservative systems instead of parabens. Our formula meets the strictest international cosmetic safety standards.
